We're not sure. Their parent company, T-Mobile hasn't updated their own yet.

 

[RumoredNow]

Since the phone is on the eligible list, rather than waiting for carrier approval use Upgrade Advisor to get the Official release (RTM).

If he uses Insider on the Release Ring, the same version is fetched as the recent public Upgrade received by supported phones (10.0.10586.xxx):

After Upgrade he can use Insider and select Production to un-enroll the phone from Insider, but at least he has W10M. WaaS (Windows as a Service) will deliver future updates within Threshold to him without any Insider access required.

Or he could stay on the Release ring and get the next public version early as Release ring in effect is the RTM. This will deliver the most stable Redstone builds to him earlier than OTA push with minimal risk.

For right now, Windows Device Recovery Tool is only flashing 8.1 to models that did not launch with 10 so it is the way to revert if he doesn't care for W10M: How can I recover/reset/restore my phone software?
